What a nice machine! Wonderfully sounding too! Makes and Ohner or Curta sound way too modern :D

It's a nice video, but i don't understand the calculation of square root. At the beginning 2 is not the square root of 8. And in the end 29960 is not the square root of 897650000, is there something I understand wrong?
